Mechanical equipment has a life span, but this life span is also affected by large human factors and has some impact on the environment. The same is true for crushers. No matter in the daily work process, we must pay attention to timely maintenance. , take good care of it. There are more and more crusher models on the market now, but the basic principles are the same, and the faults that occur are basically the same. Here is an analysis of the faults that are prone to occur in crushers in daily life.

The common failures and solutions of crushers in daily life are as follows:
1. The main bearing temperature is too high. It may be that there is insufficient grease, then you need to add an appropriate amount of grease; if the grease is contaminated, then you need to clean the bearing and replace the grease; if the bearing is damaged, then you need to replace the bearing.
2. The discharge size is too large. It may be that the crushing teeth are worn excessively, so the crushing teeth need to be replaced or surfacing welded; if the side teeth are worn or fallen off, replace them.
3. The vibration of the crusher increases. The bearing may be damaged, replace it; the gear coupling may be damaged, replace it;
4. Reduced processing capacity or insufficient power. If the hydraulic coupler leaks, then add a certain amount of No. 22 turbine oil or No. 6 hydraulic transmission oil. If the coupler is broken, it needs to be replaced with a new one; if the feed is uneven, then adjust the feed.
5. Cannot reverse automatically. If the sensor is installed incorrectly or is damaged, adjust or replace the sensor; if the sensor lead or wiring is loose, connect the lead or tighten the wiring.
6. The sensor protection system fails. If the proximity switch is damaged or the wiring in the electrical control cabinet is loose, you need to replace the switch or connect the wiring according to the wiring diagram.
In order to keep the crusher in good working condition, reduce the incidence of failures, improve work efficiency, and extend service life, we need to do daily maintenance of the crusher. It is important to pay attention to the lubrication and bearing maintenance of the crusher equipment, and prevent Crusher "on strike".
